BOLSTERSRIL FOR S PSN isitwiieitl SPECIFICATION forming part of Letters ."E'ff' I l Application Sled December 17, ISO'Z.

To all w7tc71t` zizi may concern,.-

Be it known that I, DANIEL A. Tournus, acitizen of the United States,residingatCharlotte, county of Mecklenburg, State of North Carolina; have-inventedcertain new and usei ful Improvements in Bolster-Rails for Spin- 'ningfl'ramca Twisting-Fraines, and the Like; andIl do hereby declaret'lie following to be 'a full,.clear, and exact description of the invention, such as will enable others skilled Y the-art towhichitappertains to make and use the same.

Myinvention relates to certain newand usefulimprove'mentsin'bolster-rails fopspinningframes, twisting-frames, and the lilernd is designedA particularly to dispense with the vcustomary individual lubricating feed-tube heretofore employed for supplying the lubricatingfoil to the spindle bearings or holsters and to substitute therefora reservoir common Atoan entire series of spindles and ofsuch capacity aste supply the necessary lubrication to the series without renewal during a long period of time. To this end- I substitute for the ordinary bolster-rail, of angle-iron or the like',l a hollow casting adapted to receive the lubricating-oil and provided, if desired, with a supplemental compartment or compart- 'inents whose purpose is to give any head that may be considereddesirable by the operator.' I n practice it'will be found convenient to east a number of seccato with eachother through the intermediacy of connecting-nipples, or, if preferred, the' seciions'nzay be put intoicommunication with cach other by means ol' by-pass pipes located on the rear side of the bolster-rail, so as to be out of the way.

In the accompanying drawings,` Figure l represents a cross-sectional view of a bolsterrail constructed in accordance with my invention, one of the spindles and its adjuncts being shown in elevation. Fig. 2 represents a like view with the spindle-bolster in section.

Fig. 3 represents a viewsimilar to Fig. l, but showing a diilerent and adjustable manner of connecting the spindle-bolster to the rail. Fig. 4 represents, on a smaller scale, partly broken away, a longitudinal section of the bolster-rail and supplemental head-chamber `giving suicient capacity of adjustment to ve, 727,715, dated may 12, ieee.

and illustrates a number of spindle-boisters in place.

Similar letters of reference indicate similar parts throughout the several views. l 55. The hollow bolster-rail sections may conveniently be cast and will be of suitable internal dimensions to contain a supply of lubricatingoil suiciently ample to maintain the lubrication of the bearings throughout a long-continued period of time. In the drawings, A indicates one of these sections, and ct the lubricating-oil contained therein.

The hollow bolster-rail is provided with a series of holes or apertures'spaced at suitable 65 distances apart for the reception of the bear`- ings or bolstersof tne individual spindles.' As shown in Figs; l., 2, and 4, the outershell or tube l) of each bearing is screw-threaded at c, and the receiving-apertures are correspondingly screw-threaded, so that the bearings will maintain a fixed relationship to the bolster-rail. In the modification shown in Fig. 3, however, the screw-threaded connection is dispensed with, and the relation of the bearingsto the apertures within which they have a limited play is regulable by means of the adjusting-nut (l and the screw-boit e, the aperture through which the bolt-shank passes 8o elect the limited centering movement desii-ed. The tube b of the journalbearing is perforated, so as to permit the free access of oil into its interior. Usually a few perforations will suflice; but'they mcay be increased in number, as indicated, should particular circumstances so require.

It will of course be understood that the in-. Vent-ion is applicable to spindles and spindle' holsters ol` the ordinary type, for which reason I have not thought it necessary to do more than illustrate generally a suitable con# struction, which will be well understood by those skilled in the art.

In the practice of my invention the several sections A of which the hollow bolsterraiP made upare joined together end to end, auf hereinbefore set forth, and the spindle bearings or holsters are il ierted in place with their lower ends immersed' in the body of ln- :oo bricating-oil. For most if not for all purposes and for most lubricating iiui-ds it will suice to maintain the body of oil at such a height' as to keep the spindles well submerged at the step-hearings, the oil entering freely through the apertures g. Usually, however, and in order that the supply may last for a longer period the hollow interior of the bolster-rail is lled with lubricating-oil at the outset, the supply being renewed from time to timeas required. The oil supplied to the step-bearings will in most instances readily rise to lubricate the remaining portionsof the bearing; but if it is found desirable to 'supplement the natural rise due to the rotation of. the spindle by a more positive supply his may be eiected by employing a supplemental chamber or chambers designed to give a sufficient head to positively maintain the oil at a level corresponding`to the height of the highest bearing-surface of the spindle, as indicated by the dotted line in Fig. 4. To this end a supplemental chamber B may/,be Alocated conveniently at each end of the hollow bolster-rail, so as to communicate therewith through an aperture h. The chamberB may be either a separate casting, as shownyfor it may be cast as part of the bol- 'lhe oil may be conveniently supplied to the hollow rail and to the supplemental chambers themselves through a filling-aperture in each of the supplemental chambers. By regulating the level of the oil in the supplemental chambers the level of the oil in the bearing-tubes b can be positively assured and vdetermined without relying upon the tendency of the rapidly revolving spindle tto bring the oil to the proper level should that tendency in any particular case prove insufficient.

Another element of advantage incident to my invention is that the body of oil in the bolster-rail has a tendency to keep the bolster-railv at a uniform temperature. Any tendency to heat in any one spindle would therefore be corrected by the circulation of the oil. Consequently the danger of springing or warping of the rail by heat at any one 'point is minimized.

My invention alsoy affords improved facilities for readily and efectually cleaning the bolsters and spindleswit-hout removing them from the bolster-rail. To this end the body of lubricating-oil may be drawn off at any time and its place supplied with kerosene or the like. The spindles are then again putin motion, and after the cleaning operation is completed the kerosene is withdrawn and steam or its equivalent is admitted for the purpose of removing any remaining traces of the kerosene. Afresh supply olj lubricatingoil is then admitted to the chamber.

Having thus described my invention,`what I claim isl. A bolster-rail having an oil chamber or tank for the reception of and in combination with a corresponding series of spindle bearings or holsters, said spindle bearings or bolsters dipping in common into said chamber so that the same body of oil will occupy the space about and between the submerged portions of the series of holsters; substantially as described.

2. A holster-rail having an oil chamber or tank for the reception ofl and in combination with a corresponding series of spindle bearings or holsters', said spindle bearings or bolsters dipping in common into said chamber so that the same body of -oil will occupy the space about and between the submerged pory tions of the series of vbolstersfand slot-andbolt connections between the' lrail and bolsters for centering the latter; substantially as described.

3. A bolster-rail having an oil chamber or` tank for the reception of and in combination `witha corresponding series of spindle bearings or holsters, said tank consisting of a 1ongitudinal trough -like chamber into vwhich said spindle bearings or holsters dip iu common so as to be immersed in and surrounded by the same body ot" oil; substantially as de scribed.
